Question

find the polynomial f(x) that has roots of -2, 5 of multiplicity 2. Explain how you owuld verify the zeros of f(x)

Answer 1

\[(x+2)^{2}(x-5)^{2}=(x ^{2}+4x+4)(x ^{2}-10x+25)= continue\]

Answer 2

i really dont understand this :(

Answer 3

if polinomial has a root a it means you could factor it out in the form (x-a)(rest of poliolinomil)

Answer 4

how would you verify the zeros then ?

Answer 5

just put the root instead of x and calculate. If equal 0 you would be right

Answer 6

okay ! Thanks for the help ! i appreciate it
